You must have to set a risk reward ratio like that when you win the profit can cover all the loses that is for me the risk of 100 pips with profit 10 pips it does not matter as long as we are large enough capital to withstand losses in fact look i agree every thing possible in forex but your strategy is really bad as you have to do much hard work for your strategy then if you are sure that you have high probability of getting the required results then one should go ahead with the plan
